the roof or other parts of
the building, will receive the lightning at its upper end, attracting
it so as to prevent its striking any other part; and, affording it a
good conveyance into the earth, will prevent its damaging any part of
the building.

A small quantity of metal is found able to conduct a great quantity
of this fluid. A wire no bigger than a goose-quill has been known
to conduct (with safety to the building as far as the wire was
continued) a quantity of lightning that did prodigious damage both
above and below it; and probably larger rods are not necessary,
though it is common in America, to make them of half an inch, some of
three quarters, or an inch diameter.

The rod may be fastened to the wall, chimney, &c. with staples of
iron.--The lightning will not leave the rod (a good conductor) to
pass into the wall (a bad conductor) through those staples.--It would
rather, if any were in the wall, pass out of it into the rod to get
more readily by that conductor into the earth.

If the building be very large and extensive, two or more rods may be
placed at different parts, for greater security.

Small ragged parts of clouds, suspended in the air between the
great body of clouds and the earth (like leaf gold in electrical
experiments) often serve as partial conductors for the lightning,
which proceeds from one of them to another, and by their help comes
within the striking distance to the earth or a building. It therefore
strikes through those conductors a building that would otherwise be
out of the striking distance.

Long sharp points communicating with the earth, and presented to
such parts of clouds, drawing silently from them the fluid they are
charged with, they are then attracted to the cloud, and may leave the
distance so great as to be beyond the reach of striking.

It is therefore that we elevate the upper end of the rod six or eight
feet above the highest part of the building, tapering it gradually to
a fine sharp point, which is gilt to prevent its rusting.

Thus the pointed rod either prevents a stroke from the cloud, or,
if a stroke is made, conducts it to the earth with safety to the
building.

The lower end of the rod should enter the earth so deep as to come
at the moist part, perhaps two or three feet; and if bent when under
the surface so as to go in a horizontal line six or eight feet from
the wall, and then bent again

handsomely in so short a time; therefore, seeing no prospect of an accommodation between my brother and me, he gave his consent to my returning again to Philadelphia, advised me to behave respectfully to the people there, endeavor to obtain the general esteem, and avoid lampooning and libeling, to which he thought I had too much inclination; telling me that by steady industry and a prudent parsimony I might save enough by the time I was one and twenty to set me up; and that, if I came near the matter, he would help me out with the rest.

[101] I soon after obtained, through my friend Hamilton, the printing of the Newcastle paper money, another profitable job, as I then thought it, small things appearing great to those in small circumstances; and these, to me, were really great advantages, as they were great encouragements.

You will see it, perhaps, often in this history; for, even if I could conceive that I had completely overcome it, I should probably be proud of my humility.

"That the mud, when raked up, be not left in heaps to be spread abroad again by the wheels of carriages and trampling of horses, but that the scavengers be provided with bodies of carts, not placed high upon wheels, but low upon sliders, with lattice bottoms, which, being covered with straw, will retain the mud thrown into them, and permit the water to drain from it, whereby it will become much lighter, water making the greatest part of its weight; these bodies of carts to be placed at convenient distances, and the mud brought to them in wheelbarrows, they remaining where placed till the mud is drained, and then horses brought to draw them away.

The fund for paying them was the interest of all the paper currency then extant in the province upon loan, together with the revenue arising from the excise,[163] which being known to be more than sufficient, they obtained instant credit, and were not only received in payment for the provisions, but many moneyed people who had cash lying by them invested it in those orders, which they found advantageous, as they bore interest while upon hand and might on any occasion be used as money; so that they were eagerly all bought up, and in a few weeks none.
